Item 2.     Management's Discussion and Analysis of Financial Condition
             and Results of Operations (1)

Results of Operations

Nine months ended September 30, 2001 compared with nine months ended September
 30, 2000

Revenues:

The  Partnership's  oil and gas  revenues  increased 6% to $573,649 for the nine
months ended  September  30, 2001 as compared to $540,662 for the same period in
2000. The increase in revenues  resulted from higher average prices received for
gas and natural gas liquids  ("NGLs"),  offset by lower average prices  received
for oil and a decrease in  production.  For the nine months ended  September 30,
2001,  13,049  barrels of oil,  3,835 barrels of NGLs and 39,037 mcf of gas were
sold, or 23,390 barrel of oil  equivalents  ("BOEs").  For the nine months ended
September 30, 2000,  12,935 barrels of oil, 5,029 barrels of NGLs and 35,584 mcf
of gas were sold,  or 23,895  BOEs.  Due to the decline  characteristics  of the
Partnership's  oil and gas  properties,  management  expects a certain amount of
decline  in  production  in the  future  until  the  Partnership's  economically
recoverable reserves are fully depleted.

The average price received per barrel of oil decreased $1.03, or 4%, from $28.34
for the nine months  ended  September  30, 2000 to $27.31 for the same period in
2001. The average price received per barrel of NGLs increased  $.92, or 7%, from
$13.72  during the nine months ended  September  30, 2000 to $14.64 for the same
period in 2001.  The average  price  received per mcf of gas  increased 40% from
$2.95  during the nine  months  ended  September  30, 2000 to $4.13 for the same
period in 2001. The market price for oil and gas has been extremely  volatile in
the past  decade  and  management  expects a certain  amount  of  volatility  to
continue in the  foreseeable  future.  The  Partnership  may therefore  sell its
future  oil and gas  production  at  average  prices  lower or higher  than that
received during the nine months ended September 30, 2001.

Costs and Expenses:

Total  costs and  expenses  increased  to  $331,393  for the nine  months  ended
September  30,  2001 as compared  to  $315,058  for the same period in 2000,  an
increase of $16,335,  or 5%. This  increase was due to  increases in  production
costs and general and  administrative  expenses ("G&A"),  offset by a decline in
depletion.

Production  costs were $292,217 for the nine months ended September 30, 2001 and
$276,533  for the same period in 2000  resulting in a $15,684  increase,  or 6%.
This  increase was  primarily due to higher ad valorem  taxes,  additional  well
maintenance  costs incurred to stimulate well  production and higher  production
taxes associated with higher revenue prices.

G&A's  components are independent  accounting and engineering  fees and managing
general partner personnel and operating costs. During this period, G&A increased
4% from $18,306 for the nine months ended  September 30, 2000 to $19,118 for the
same period in 2001 primarily due to a higher percentage of the managing general

                                        8

partner's  G&A being  allocated  (limited  to 3% of oil and gas  revenues)  as a
result of increased oil and gas revenues.

Depletion  was $20,058 for the nine months ended  September 30, 2001 as compared
to $20,219 for the same period in 2000, a decrease of $161, or 1%.

Three months ended September 30, 2001 compared with three months ended September
 30, 2000

Revenues:

The Partnership's  oil and gas revenues  decreased 21% to $151,803 for the three
months ended  September  30, 2001 as compared to $191,130 for the same period in
2000. The decrease in revenues resulted from lower average prices received and a
decline in  production.  For the three months ended  September  30, 2001,  4,005
barrels of oil,  1,491 barrels of NGLs and 11,206 mcf of gas were sold, or 7,364
BOEs. For the three months ended September 30, 2000, 4,072 barrels of oil, 1,737
barrels  of NGLs and  12,327 mcf of gas were  sold,  or 7,864  BOEs.  Due to the
decline characteristics of the Partnership's oil and gas properties,  management
expects a certain  amount of  decline  in  production  in the  future  until the
Partnership's economically recoverable reserves are fully depleted.

The average  price  received per barrel of oil  decreased  $3.77,  or 12%,  from
$30.26 for the three  months  ended  September  30,  2000 to $26.49 for the same
period in 2001. The average price  received per barrel of NGLs decreased  $3.20,
or 22%, from $14.80  during the three months ended  September 30, 2000 to $11.60
for the same period in 2001. The average price received per mcf of gas decreased
26% from $3.42 during the three months ended September 30, 2000 to $2.54 for the
same period in 2001.

Costs and Expenses:

Total costs and  expenses  increased  to  $106,778  for the three  months  ended
September  30,  2001 as compared  to  $104,589  for the same period in 2000,  an
increase of $2,189,  or 2%. This  increase was due to increases in depletion and
production costs, offset by a decrease in G&A.

Production  costs were $94,767 for the three months ended September 30, 2001 and
$93,508 for the same period in 2000 resulting in a $1,259  increase,  or 1%. The
increase was primarily due to a higher ad valorem taxes,  offset by a decline in
well maintenance  costs and lower production taxes associated with lower oil and
gas prices.

During this  period,  G&A  decreased  33% from $6,974 for the three months ended
September  30,  2000 to $4,670 for the same period in 2001,  primarily  due to a
lower percentage of the managing general partner's G&A being allocated  (limited
to 3% of oil and gas revenues) as a result of decreased oil and gas revenues.

Depletion  was $7,341 for the three months ended  September 30, 2001 as compared
to $4,107 for the same period in 2000,  representing  an increase of $3,234,  or
79%. This increase was attributable to a decrease in proved reserves as a result
of lower  commodity  prices for the three  months  ended  September  30, 2001 as
compared to the same period in 2000.

Liquidity and Capital Resources

Net Cash Provided by Operating Activities

Net cash provided by operating  activities  increased  $101,592  during the nine
months ended  September 30, 2001 from the same period ended  September 30, 2000.
This  increase  was due to an increase in oil and gas sales  receipts of $32,318
and a reduction of $85,770 in working capital, offset by increases in production
costs of $15,684 and G&A expenses of $812.  The increase in oil and gas receipts
resulted from  increases in gas and NGL prices during 2001 which  contributed an
additional  $46,447 to oil and gas receipts,  offset by a decrease of $14,017 in
oil prices and a decline in  production  of $112  during 2001 as compared to the
same period in 2000.  The  increase in  production  costs was  primarily  due to
higher ad valorem taxes, additional well maintenance costs incurred to stimulate
well production and increased  production  taxes  associated with higher revenue
prices.  The increase in G&A was  primarily  due to a higher  percentage  of the
managing  general  partner's G&A being  allocated  (limited to 3% of oil and gas
revenues) as a result of increased oil and gas revenues.

Net Cash Used in Investing Activities

The Partnership's  principal  investing  activities during the nine months ended
September  30, 2000 were related to upgrades of oil and gas  equipment on active
properties.

Net Cash Used in Financing Activities

For the nine months ended September 30, 2001, cash distributions to the partners
were  $243,114,  of which $60,553 was  distributed  to the general  partners and
$182,561 to the limited partners.  For the same period ended September 30, 2000,
cash  distributions  to  the  partners  were  $243,035,  of  which  $61,165  was
distributed to the general partners and $181,870 to the limited partners.

During  2001,  the  Partnership  made  distributions  in  March  and July but no
distributions  were made by the Partnership during September pending the vote of
the proposed merger of the Partnership into Pioneer Natural  Resources USA, Inc.
("Pioneer USA"). For further information, see "Proposal to acquire partnerships"
below.

Proposal to acquire partnerships

On October 22,  2001,  Pioneer  Natural  Resources  Company  ("Pioneer")  mailed
definitive materials (the "proxy  statement/prospectus") to solicit the approval
of limited partners of 46 Parker & Parsley limited  partnerships,  including the
Partnership,  of an agreement and plan of merger among  Pioneer,  Pioneer USA, a
wholly-owned subsidiary of Pioneer, and those limited partnerships.  The special
meetings of the limited partners to consider and vote on the merger proposal are
scheduled  for  December  20,  2001.  The record  date to  identify  the limited
partners who are  entitled to notice of and to vote at the special  meetings was
September  21, 2001.  Each  partnership  that approves the agreement and plan of
merger and the other related  merger  proposals will merge with and into Pioneer
USA.  As a result,  the  partnership  interests  of those  partnerships  will be
converted into the right to receive Pioneer common stock.
